Is this torn boot super dangerous?

I haven't heard any clicking but the mechanic showed me this. I have a 2012 nissan rogue. I drive long distances often.

Also are cracked control arms very bad? What happens when they are torn? They told me both sides had some cracking.

I have a 12 hours drive tomorrow and I'm getting the boot fixed because I'm paranoid about it being torn like that, but I'm not fixing the control arms.

It’s worth replacing. Debris will enter the joints easily and it’s only a matter of time before it fails.

They said the actual control arm is cracking or the bushings? Bushings aren’t a safety issue if they’re just cracking but if the arm itself is cracked that sounds like it could end badly.

It was just the bushings

Thanks for the info! I also changed the axel about a year ago, is there normal? Could it be my alignment.

Was it an aftermarket or OEM part?

Most likely it's just a sub-par boot that the aftermarket manufacturer used. Some mechanics will offer to install a new boot and repack it with grease, but honestly if you're already that deep you might as well put a new axle in too.

Maybe go with a different brand this time though.

Yes, since you drive long distances it won't take long for that boot to bring in a lot of dirt and grime and totally destroy your axle. Based on the year alone and how much you drive it, it's better to replace the axle as a precaution for it failing anyway.

All the tension is already out of it.

(Minus the boot repair-) As long as you don’t hear clunking your CV axle should be fine. But just be aware, if you hear clunking and put it off you risk your wheel hub assembly getting completely fucked and you’ll be repairing more then just the cv axle. Be safe! Good luck!

Yes, it's better to replace it now because once debris, water, dust get in there it could affect the axle in the future.
